JURY-RUDDER.

SPECIFICATIONim-ming part of Letters Patent No. 367,871, dated August 9,1 57.

Application filed March 17, [SE6 Sciial No. 195,601. No model To all whom, it mayconccrn: Be itknown that l, JOSEPH W ALL, of Bootle, in the county of Lancaster, England, have invented certain new and useful Improvements in Jury-Rudders; and I do hereby declare that the following is a full, clear, andexact description of the invention,which will enableothersskilled in the art to which itappertains to make and use the same, reference being had to the accom; panying drawings, and to letters of reference marked thereon, which form a part of this specification.

1 Figure 1 is a side elevation of a part of a ships hull with my invention attached there to. Fig. 2 is a plan of the clamp for-holding the rudder, which is attached to the vessel under its steru-quarter,"and which is bolted to the dBZtd-WOOd or stern-post. Fig. 3 isa plan of the clampsfor securing the blade of therudder to the stem thereof. Fig. 4 is a plan ofthe bearing for the rudder-stem,that is attached to the stern of the vessel near the top of the rudder-stem. Fig. 5 is a vertical section of the socket, into which the'lower end of the rudder-stem is stepped, and of the thimble and lower end of the rudder-stem. v p N The sameletters show like parts.

My invention relates to jury or spare rudders for ships and vessels of all descriptions,

By a jury-rudder I mean that one which can be supplied and rigged to vessels to take the 'place of the permanent steering apparatus when it has been disabled or carried away'by an accident or disaster at sea.

My jury-rudder I design to attach'to thestern of the vessel directly in a line abaft of the permanent or regular ships rudder.

The stem of the rudder is seen at a. This may be a main boom or spar, or it may be a stick specially carried on board for the purpose; but I desire to specify that any spar or n stick having a :uniform diameterthroughout its length-such as vessels usually carry'as extra spars-can.be utilized for this purpose. This spar-,Which I will now call the rudderstem, is seen ata. To this,at the lower portion thereof, is attached the blade by The blade may be'of one or more parts or pieces,

' and may be provided beforehand and carried on board the vessel at the commencement of the voyage. It can be made of wood or metal.

of the stern opposite to where the blade I) islo- A cated. Bringing these lips d together binds the semicircular parts closely to the stem t. The straight partsf-lie along on the-two faces of the blade b, and the bolts 9 pass through the blade, as shown in the drawings, and thus hold the blade in its. time relation and contact with the stem and clamp it firmly thereon. The lower end of the stem 4 is stepped intoa sock ct,- h. This socket is made cpncave on theupper surface to receive the lower end of thestem, and

the neck i ofthethimble. The lower end of the stem to fits into an iron thimble, j, which has a hole through it, through which projects thirnble forms what I call the lower end of the stem. The thimble is properly secured by bolts It. It is of thick iron at the bottom, and is secured in its'seat in the socket h by the screw-bolt l, which threads up into a screwsocket in the lower end of the neck 2'.

' The socket h is the support of the 81261110. at the lower end This socket h is suspended, supported,-and held by guys m and 'n. The

i guys m extend upwardly and forwardly and run through hawse-ports in the vessels bultends abaft of the stern of the ship and is secured into the eye 0 on the boom 72?, provided for the purpose. The socket h is furnished with proper eyes to receive the guys.

warks and are secured aboard. The guy a ex- The guys are of wire rope, so as .tobe practically non-ela'st,ic, or chains. We have then got the rudder securely stepped at the lower end and provided with a socket, Ii, in which the lower end of the stem can turn as the rudder is moved The screw-bolt Z keeps the lower end of the stem downin its socket h. The stem for steering.

is further held by the clamp 10. This clamp is composed of two strong metal barsbolted together, as seen in the drawings. The portions 1) pass on each side of the hull at the stern an d the bolts q pass through the dead wood orsternpost of the vessel and through the portions 1), and so fasten the clamp firmly to the vessel. The two semicircular portions of the clamp encompass the stem, but so as to allow it to turn therein in steering. Thelipsr serve to fasten the two parts of the clamp together at the stern side of the stem. The stem is provided with a metal band, s, inside of the circular part of the clamp, in order to avoid chafing. This is seen at t. The clamp p is supported by three rods, -u o c.

v v are diagonal rods (with tightening-nuts w) bolted to the ships side and connected with the clamp p at The other red is seen at u, fastened to the ships stern at the center and attached to the clamp at y by a bolt passing through the bifurcation of the rod at its lower end as well as through the two parts of the clamp p itself. Near the top of the stem it is further fitted with a bearing, .2. This is composed of a metal plate, a, bolted to the ships stern at the proper point and having a semicircular socket, I); also, of the cap-piece 0', so

that the two will, when placed together, form the circular hole seen in Fig. 4, and the two parts be united by bolts (1 passing through the lips 0. At this point, also, the stem is protected by a chafing-ring of metal, f, to protect the wood of the stem. g is the tiller, projecting directly astern and properly fastened and clamped to the stem of the rudder.

The tiller can he applied so as to project forward of the stem of the rudder, where the nature and structure of the vessels admit. In

case ofsea-going steamers it would be necessary to have it as before described. The tiller is provided with blocks and ropes reaching aboard the vessel, and is worked thereby. These ropes can be operated by winches, or, in the case of sailing vessels, by the barrel of the steering apparatus aboard. Lines h are also attached to the blade of the rudder, as illustrated. They run through sheaves at t" and are worked at the same time with the tiller-lines in order to facilitate the turning of the rudder.

I have thus produced a j ury-rudder that can be quickly shipped, in case of an accident, to the permanent steering apparatus and firmly secured in place.

It will be seen that the guys m and it serve to steady the rudder and take the strain during forward or backward motion of the vessel.

\Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, 1s-

1. The combination of the stem (1., blade 1/, bltldGClttlllPS 0, having thelips (Z, semicircular parts 0 and straight partsf, the thimble at the lower end of the stem, with its neck 1 and boltl and chafing-ring f and band s, as herein set forth.

2. The combination of the stem a, having the thimble, as set forth, blade I), clamped, as described, with the clamp 11, to hold the stem to the vessels hull, as described, the supports a o, bearings 1/, metal plate 11., cap-piece c, the socket Ii, to support the lower end of the stem, and guys at and n, as herein specified.

In testimony that I claim the foregoing as my own I al'tix my signature in presence of two witnesses.

JOSEPH \VALL.
